Gully Density

AUS-TMI-IND-GUL General Moderate confidence

Benchmark Value

0 m/ha
Direction: Lower is desirable ↓
Form: Point

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

The objective of "no gully formation" translates directly to a gully density of 0 m/ha for new, active gullies.

Metric Definition:

gully density—the total length of active gullies per unit of area

Benchmark Definition:

The benchmark represents the best available condition for newly constructed landforms on industrial sites, where the primary objective is long-term geomorphic stability.

Justification:

It is derived from explicit, quantitative completion criteria in statutory and draft mine closure plans, which define successful rehabilitation by the absence of significant gully formation (e.g., "no gully formation >0.5m depth").

Notes

Lower Critical Threshold: 0 m/ha. Upper Detrimental Threshold: 0 m/ha. The upper detrimental threshold is crossed when gully density becomes > 0 m/ha. This transition is understood as the crossing of a predictive geomorphic threshold defined by landform design and material properties.
